Presentation Transcript

  1. Status report 11/29/04(see also transparencies by Russ Rucinski on the solenoid status) M.Weber, FNAL AEM Dzero, M.Weber

  2. Ground isolation • On Tuesday we powered down the detector and electronics in order to disconnect the safety ground (we had indications that there was a grounding violation). • Found that the resistance was 5 Ohm • After removing some cables, which we found to be shorting the grounds, the resistance went up to 5 kOhm • Wednesday spent in turning the detector on again. • We still see some effect from welding in the form of noise in the calorimeter: further investigating AEM Dzero, M.Weber

  3. Status • We have switched to the new online system(major issues fixed last week, minor fixes underway) • S&S since Wednesday evening • All the readout crates are running in a DAQ exercising mode • Spoke election polls close today 2400 • Solenoid -> see transparencies by Russ R.
